ABOUT THE GAME
Citadel: Fortress Defense is a 3D medieval strategy game in first person. Each day you build your town, then a raid comes. Build walls, gates, houses, farms, sawmills, quarries, towers, barracks, a market and a mage tower. Gather wood, stone, gold and food. Characters: you are the Lord. Hire knights, archers and mages and control any soldier in battle. Enemies: goblins, bandits, skeletons, shamans and enemy soldiers break through walls; every fifth day a boss arrives. Each raid is stronger: spend renown on upgrades, raise stone walls and expand your land. Mode: single player endless survival. If the town hall falls, the game is over.

STRATEGY & TIPS FOR CITADEL: FORTRESS DEFENSE
Think a move or two ahead and consider your opponent's likely response before committing.
Defend key positions rather than spreading your forces thin across the whole board or map.
Secure your resource generation before expanding your army or territory — a stronger economy compounds every turn after that.
Don't commit your whole force to one engagement — keep a reserve for whatever the fight leaves exposed afterward.
